Abstract

A method for automated decision making includes using situated agents with real time reactivity skills for making decisions according to their individual perceptions and motivations, and further includes integrating into the situated agents one or more pre-established plans by using a model representing sequences of causally related events for supporting the decision making to fulfil coordinately the one or more pre-established plans.

Claims

1. A method for automated decision making, comprising using one or more situated agents with perceptions and real time reactivity skills for making decisions according to their individual perceptions and motivations, wherein said method further comprises integrating into said situated agents one or more pre-established plans by means of a model representing sequences of causally related events for supporting said decision making to fulfil coordinately said one or more pre-established plans.

2. The method as claimed in claim 1, wherein said model associates a possibility and a necessity value to at least part of said events.

3. The method as claimed in claim 2, further comprising building said model, for determining the possibility, necessity and probability of said events, by means of performing the following steps:

a) stating or discovering events which are internal and/or external to a causal sequence and temporal precedence relations among them;

b) establishing or discovering relations between the possibility and necessity values of the events from said temporal precedence relations and kinds of events, including if they are internal or external; and

c) quantifying the temporal latencies within said order relations.

4. The method as claimed in claim 3, wherein:

said internal event is one whose occurrence is conditioned by events having started previously within the causal sequence

said external event is one that could possibly occur within a sequence of events, and even condition the occurrence of other internal events, but whose possibility of occurrence is not conditioned and must, therefore, be estimated by an external method.

5. The method as claimed in claim 4, wherein said statement or discovery of events of step a) comprises stating one or more immediate predecessors for each event, and stating that the start of an event must be posterior to the start of his immediate predecessor or predecessors, and hence state that each event presents order relations forming a lattice with his immediate and non-immediate predecessors.

6. The method as claimed in claim 3, wherein said step b) comprises determining the possibility and necessity values of each internal event as a function of:

its cause, wherein said cause is one preceding event, unique or out of several candidates, regarding possibility and/or necessity values and/or occurrence, and/or

its context, wherein said context is one or several of the said immediate and non-immediate predecessors.

7. The method as claimed in claim 3, further comprising updating at run time the possibility and necessity values of each of the events from temporal latencies established beforehand and/or information obtained at run time by a physical model or any other external source.

8. The method as claimed in claim 7, further comprising transforming the specification of events resulting from steps a), b) and/or c) and integrating it into a physical system constituting one or more said situated agents.

9. The method as claimed in claim 8, wherein said physical system is an information processing device selected from one of an electric and/or electronic processor and a biological processing device.

10. The method as claimed in claim 9, wherein said electric and/or electronic processor implements simulations of a biological physical system.

11. The method as claimed in claim 9, wherein said situated agent make said decisions using said real time reactivity skills according to a behaviour-based network or an extended behaviour-based network, or EBN

12. A method as claimed in claim 11, further comprising embedding said specification of events into at least part of said situated agents without overwriting the skills previously embedded, informing the situated agent that each event can:

be executed by any agent with access to the needed resources and/or

be used as the cause or part of the context of another event and/or

be estimated with some estimation method

13. The method as claimed in claim 12, further comprising building candidate sequences of events by performing steps a), b) and/or c) from real time perceptions and/or previously established or declared sequences of events

14. The method as claimed in claim 13, further comprising integrating statistical learning methods within at least part of said situated agents, for adjusting events relations within sequences of events.

15. The method as claimed in claim 14, further comprising ranging and selecting said candidate sequence of events by dynamically evaluating them.

16. The method as claimed in claim 3, further comprising transforming the specification of events resulting from steps a), b) and/or c) and integrating it into a physical system constituting one or more said situated agents.

17. The method as claimed in claim 8, further comprising embedding said specification of events into at least part of said situated agents without overwriting the skills previously embedded, informing the situated agent that each event can:

be executed by any agent with access to the needed resources and/or

be used as the cause or part of the context of another event and/or

be estimated with some estimation method

18. The method as claimed in claim 3, further comprising building candidate sequences of events by performing steps a), b) and/or c) from real time perceptions and/or previously established or declared sequences of events

19. The method as claimed in claim 8, further comprising integrating statistical learning methods within at least part of said situated agents, for adjusting events relations within sequences of events.

20. The method as claimed in claim 18, further comprising ranging and selecting said candidate sequence of events by dynamically evaluating them.
